# This script takes a pLaTeX file and generates a collection of
# png or ppm image files, one per previewed snippet.
# Example usage:
# lyxpreview-platex2bitmap.py ppm 0lyxpreview.tex 128 000000 faf0e6

# This script takes five arguments:
# FORMAT:   The desired output format. 'ppm'.
# TEXFILE:  the name of the .tex file to be converted.
# DPI:      a scale factor, used to ascertain the resolution of the
#           generated image which is then passed to gs.
# FG_COLOR: the foreground color as a hexadecimal string, eg '000000'.
# BG_COLOR: the background color as a hexadecimal string, eg 'faf0e6'.
